Help!
I was about to purchase a Nano for use with ex1 & ex3,
However, the launch of the Ki pro mini using 220mbps I frame Prores codec has made me stop and ponder...
Nano xdcam long GOP 8 bit 422 codec or the aja mini using Prores.
I would assume I frame Prores recording offers some advantages during the edit stage? But if my work does not include much colour correction and my final output is either DVD or Blu-ray and image quality is my holy grail then which recorder would be best?
I seem to remember reading somewhere (maybe on this forum) that Alister did a comparison between XDCAM EX long GOP and Prores I frame.
Can somebody offer some purchase advice?
Many thanks
Andy

On an EX1 or EX3 the cameras highish noise floor will largely cancel out any possible advantage that 10 bit may give over 8 bit. Basically the 8 bit codec can fully resolve the image noise, so all going to 10 bit does is waste data on noise information. I find the ProRes codec itself to be a little on the noisy side. Also if you want to use 220Mb/s ProRes you will have to spend a lot more on your media as you need to performance CF cards and you will fill them up at least twice as fast as using a NanoFlash at 100Mb/s long GoP (the sweet spot for quality/performance).

Looking ahead as cameras get quieter (better than 59db) then 10 bit starts to make more sense. So maybe the Ki-Pro may be a better long term investment. Personally I love my NanoFlashes, they have proved to be solid and reliable and the low power consumption means running it of a Swit EX battery with D-Tap is easy.
